Summary of the invention
(problems to be solved by the invention)
As above-mentioned one of synchronous motor, have by continuously connecting realize triangle connection construction, but
With on the stator tooth of phase mutually separated, the quantity for connecting the connecting line of coil is more, needs to configure space or the bus of connecting line
Substitutions of elements such as (bus bar).In addition, connecting line is not the generation for facilitating the magnetic force of stator, it is desirable to be reduced as far as.
The present invention is researched and developed in view of such situation, and its purpose is to provide a kind of changing for coil by stator
The good technology to realize small-sized, high torque (HT) brushless motor.
(means for solving the problems)
The brushless motor of a scheme of the invention includes: stator, has cricoid stator core and the inner circumferential side in stator core
The the 1st~the 12nd tooth circumferentially successively set；1st~the 12nd coil is wound in the 1st~the 12nd tooth respectively, and by triangle
Connection；And rotor, it is arranged on the central part of stator.About the 1st~the 12nd coil, the coil of the 12nd, the 1st, the 6th and the 7th is gone here and there
Connection connects and composes W phase, and the coil of the 8th, the 9th, the 2nd and the 3rd, which is connected in series, constitutes U phase, the coil quilt of the 4th, the 5th, the 10th and the 11st
It is connected in series and constitutes V phase；In configuration on tooth, identical, the adjacent isopen of the adjacent mutual winding direction of out-phase coil
It is reverse to enclose mutual winding direction.W phase has the 1st connecting line of the 1st coil and the 6th coil of connection.U phase has the 9th line of connection
2nd connecting line of circle and the 2nd coil.V phase has the 3rd connecting line of the 5th coil and the 10th coil of connection.
With this solution, the mutual connecting line of coil that connection mutually separates can be used in shorten.In addition, the last line and V of U phase
The initial line of phase is drawn from adjacent coil, alternatively, the last line of V phase and the initial line of W phase are drawn from adjacent coil, alternatively, W
The last line of phase and the initial line of U phase are drawn from adjacent coil, therefore the processing that coil is wound in the whole story line after each tooth is relatively held
Easily, and connection also shortens.Therefore, the amount that can be reduced the coil of the non-generation for facilitating magnetic force can reduce coil resistance, and can subtract
The configuration space of small coil.
1st~the 3rd connecting line may be configured to mutually disjoint the mode of fork.Insulating reliability can be sought as a result,
It improves, it helps slimming, the miniaturization of motor.
1st~the 3rd connecting line can be configured in the outer edge of an end face in the axial ends face of stator core.1st connects
Wiring and the 3rd connecting line can be configured in from axial and see a part overlapping and positions different in the axial direction.2nd connecting line
With being indexed to the zigzag part of the top of the 1st connecting line from axial see from below the 3rd connecting line.Stator seen from above as a result,
When the item number of connecting line that is overlapped become 2 hereinafter, facilitating the slimming of motor, miniaturization.
In addition, by any combination of the above constituent element, the form of expression of the invention in component, manufacturing method, system etc.
Between transformed scheme, as technical solution of the present invention and effective.

The identical between cog of adjacent windings is drawn, alternatively, the last line of W phase and the initial line of U phase are drawn from the identical between cog of adjacent windings, therefore
The processing of whole story line after coil to be wound in each tooth becomes easy, and connection also shortens.Therefore, it can be reduced the generation not to magnetic force
The amount of helpful coil can reduce coil resistance, and can also reduce the configuration space of coil.That is, can be by stator
Coil winding method improvement to realize small-sized, high torque (HT) brushless motor.
The mode of fork in addition, the 1st connecting line F3 of connecting line F1~the 3rd of present embodiment is configured to mutually disjoint.
Connecting line will not contact each other as a result, can seek the raising of insulating reliability, and facilitate the slimming of motor, miniaturization.More
Specifically, as shown in figure 5, the 1st~the 3rd connecting line F1~F3 by arc-shaped is configured at the both ends of the axial Ax of stator core 36
The outer edge 14a of the insulator of one end face in face.1st connecting line F1 and the 3rd connecting line F3 are configured in from one in terms of axial Ax
It partly overlaps and positions different in the axial direction.Also, the 2nd connecting line F2 has from the axial lower section seen from the 3rd connecting line F3
It is indexed to the zigzag part F ' of the top of the 1st connecting line F1.As a result, seen from above stator when the item number of connecting line that is overlapped 2
Item is hereinafter, be also beneficial to the slimming of motor, miniaturization.
In addition, the back part (outer peripheral surface) in each insulator 40 is formed with the engaging portion of the movement for controlling each connecting line
40a.It as a result, can be in the fixed each connecting line in desired position.Especially the 2nd connecting line F2 of present embodiment, in zigzag part
The front and back of F ' is supported from different directions by 2 engaging portion 40a, so that it is able to achieve the state with tension (tension), thus it is firm
Admittedly be fixed on desired position.
